Pull ARM SoC fixes from Olof Johansson:
 "Only one remaining fix for arm-soc platforms at this time, a small
  bugfix for cpu hotplug on highbank platforms that has become much
  easier to hit as of late.

  Details in the patch description, but it's small and well-contained
  and definitely impacts users of the platform, so 3.9 seems
  appropriate."
